TRACTION-ENGINE. a I x 3 Application filed August 2, 1910, Serial No.

To all 107mm it may concern:

Be it known that I, SAMUEL S. Mormon, a citizen of the United States,and a resident of Upper Sandusky, in the county of and State of Ohio,have invented a new "and Improved Traction-Engine, of

following is a full, clear, and exact description.

My invention relates to traction engines 10 such as are used foragricultural and other purposes. o-

The object of my invention is to so construct the tractor that the powerwill be distributed evenly to the driving wheels and of operation willbe obtained with a construction that is strong, yet flexible as regardsaccommodating itself to inequalities of the ground.

The invention will be fully described 20 hereinafter with reference tothe accompanying drawings, which represent one form of my improvedtractor, and the novel features will be pointed out in the appended iclaims.

In the drawings, Figure 1 is a plan view of the tractor, with parts insection; Fig. 2 is aside elevation of the machine; Fig. 3 is ahorizontal section on an enlarged scale, showing the drive shaft and thegearing Fig. 4 is a vertical section on the line H of Fig. 5; Fig. 5 isa vertical cross section, on the line 5-5 of Fig. i; Fig; 6 is a detailhorizontal section of-the differential gear on the axle; and verticalsectionon the line 7-7 of Fig. 3, showing a detail of the speedchaugingmechanism. I a

The engine proper may be of any suitable construction. I have shown twoopposed slightly out of set 3, and containline, as may be seen in Figing pistons, such as 11 which, by means 0 rods 12, are connected withopposed cranks 13 on the main shaft or drive shaft 14:, jour;

45 naled in the crank case 15 and preferably carrying a fly wheel 16.When the engine,

is a high-speed engine (as the one shown mthe drawings is supposedtobe), a counfrom the main shaft 14 i at a reduced rate of speedhby" meansof a pinion 18'- meshing with gear wheellt), each of said wheels "beingrigid upon its shaft. On thcountersh aft-L17 are mounted looselythepinions 20 and 21, and rigidly Specification of Letters Patent.

pinions 20 and 24 respectively, between which is located the drivinoclutch member 25, v i with the shaft. 17 but capable of being shiftedlengthwise thereof to engage either one of the clutch disks 23and 2i.

The particular mechanism for shifting the clutch member shown in thcdi-awings, particularly F igs'. 1, 3 and 7', 1s constructed as follows:The shaft 17 has a longitudinal slot 17, through which extends: a bar 25secured rigidly to the clutch member 25. The bar has a central threadedopening into which fits the adjusting screw-rod 26, located in anaxialrece ss of the shaft 17 and capable of turniu i relatively thereto,although under nor mil condition the shaft 17 and the 1 26 rotate inunison. Longitudinal displacement of the rod relatively to the shaft isprevented in any suitable manner, as by anut 26 at the inner portion ofthe rod and a pin 26? passing through the nut and rod; At the outer endof the rod 26 is abevel wheel26, in mesh with another bevel wheelfZYcarried by a short transverse shaft 28. journaled in a sleeve 29 whichis compelled, asby a set screw 80, to rotate with the shaft 17. On theshaft 28 is also secured rigidlya pinion 31, in mesh with a" rack 32carried by a slide 32, which is movable lengthwise of the shaft 1'7 inthe'sleeveQS),butheld vto rotate with said sleeve, the racl; sliding ina groove of the shaft. To. shift flier-tick, the outer end of the, slidehas a grooved collar 32", engaged by the forkedlend of a shifting lever33, f'ulcruxriedatBS:and ;0perated by means of unsuitable hand lever 33.The pinion 31isQofgreater diameter than the bevel wheel 26?, so that,name; will not interfere with tlie fmouement of f the, rack. In the.central or neutral.,;position 25 i ak id y;

(Fig. '3);;the-clutch member 7 so that the tractor or truck will stand(5 11 while the motor (generally a gasolene enpine) is running. Thepinion20 is in mesh with a gear wheel keyed on the transmission shaft35, and similarly the "pinion '21 is in mesh with another gear likewisekeyed on the shaft The pitch ratios of these two sets ,of gears-aredifferent, so that one oflthen'i (for insta-nceffll, 36) willoperate'the transmission shaft at 2i areiclutch disks E i-land held torotate wheel 36, c

a higher rate of speed; than the: other 20,

3%)1 lhercfore, according to the engage anot er in which the ends of thesections of the axles are journaled at the longitudinal. centeroftherigid frame, the strain of the driiring Wheels from contact with'u-nevetror rough ground or for any other cause, is prevented from beingcommunicated to the frame and the frame thereby relieved of alltorsional strain. This construction also relieves the several bearings.of strain. By arranging the engine at center of the frame, between thefront and rear wheels, theweight is equally distributed upon the fourwheels.

The steering mechanism comprises a steering wheel 78 on a shaft 79,journaled in brackets 80 of the gear case 77 and provided with worms 81,one of which engages the upper portion of a worm-wheel 82 and the otherthe lower portion of a worm-wheel 83. T hese worm-wheels are mounted onshafts 84, and to each shaft are secured the inner ends of two chains85, their outer ends being secured to eyes 86 embracing the axles 61near their outer ends,'projections 61 serving to prevent the eyes 86from slipping inward. During steering, one of the chains of each axlewill be pulled inward to turn the axle, while the other chain will behauled in so as'to prevent it from becoming slack; when steering in theopposite direc tion, the functions of the, chains will be reversed. Incases where the motor is not a high speed motor, the speed-reductiongear l8, 19 may be omitted, that is to say, the shaft 17 may be thecrank shaft of the motor. A canvas apron (not shown) may he provided toexclude dust and catch dripping oil, etc. I

Various modifications may be made with out departing" from the nature ofmy invention as set forth in the appended claims.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent:

2. A motor vehicle, comprisin a rigid frame, front and rear axles'each'ormed of two sections, ground wheels on the axles, gear casings inwhich the inner ends of the sections of the axles are mounted, means forpivoting each gear of line with the axle and substantially at thelongitudinal center of the frame, difierential gearing in each gearcasing and honnecting the sections of the axle, each dili'ew entialgearing: including a chain wheel, a transmission mounted in the'fran ehe tween-the axles, differential gearing on the transmission shaft andincludingtwo chain wheels, and chains passing around the c I wheels ofthe trar mission shaft 11 in a motor rchzc ing a depending memberintermediate of its ends, front and rear axles, ground Wheels on theaxles, centrally arranged gear casings in which the axles are mounted,gearing in casings for operating the axles, a halland socket jointbetween the frame and the gear casing of the front axle, said ball andsocket joint being in rear of said axle, a king bolt connection betweenthe frame .-'l-the gear casing o'f the rear axle, said bolt being; infront of said axle, rods l lflu-Jifg one end pivoted to the lowerportions of the casings and their other ends pivoted to the center ofthe depei'iding member of the a transmission shaft, and means foroperating the gearings of the gear casings from the transmission shaft.
